Machine tool

A machine tool for machining workpieces (22), comprising three NC-controlled linear axes orthogonal to each other, namely a horizontal X-axis, a horizontal Y-axis and a vertical Z-axis, with a machine base (10), which comprises two vertically upwardly directed side beds (12) that are spaced from each other in the X-axis, with a bridge (28) displaceably guided in the Y-axis on top of the side beds (12), with a Z-slide disposed at the center of the bridge (28) in relation to the side beds (12), which slide can be displaced in the Z-axis and carries a tool spindle (46), with an X-guide element (14) disposed on the machine base (10), with a workpiece holder element (16, 18, 20) displaceable on the X-guide unit, and with a tool holder disposed on the tool spindle (46),

• characterized in that the axis of the tool spindle (46) intersects the Z-axis and that the tool spindle (46) can be rotated by NC-control about an axis (C-axis) coinciding with the Z-axis, for which purpose the Z-slide (36) is mounted in the bridge (28) rotatably about this C-axis.
